Especially in anterior region impacted canines may be present. In some cases when orthodontic extrusion is not possible, surgical approach can be a valid treatment plan. But large bone defects created after the extrusion often requires bone grafting. In such cases, guided bone regeneration is a good strategy to form new alveolar bone. Aim/ hypothesis: Removing impacted teeth cause large bone defects. In this case report, we increased the bone volume by using bone grafts and membranes. Material and Methods: A 55 years old male patient was referred to Istanbul University Dentistry Faculty Department of Oral Implantology due to mobile maxillary teeth. After the clinical and radiological examination, full arch fixed prosthesis was planned. A horizontal impacted canine was present where the implants will be placed. A guided bone regeneration was planned on the same day as tooth extraction. After canine extraction, Xenograft and Collagen membranes were used to increase horizontal volume of alveolar bone and to fill the extraction socket of canine. Membrane was fixed with pins. Two mini-implant were used for temporary fixed prosthesis. After a healing period of six months implants were placed. Screw-retained metal ceramic prosthesis was used for final restoration. Augmented site and implants were controlled regularly with CBCT after surgery. Results: During postoperative 1 year controls, there was no change in gingival contour and bone resorption with CBCT. Pink esthetic score was used to evaluate gingival aesthetic. Implants healed without adverse events. The comparison of radiographic images showed physiologic bone remodeling at the implant shoulders without bone resorption. Conclusion: Volumetric analysis showed a low degree of contour changes from extraction and implant placement to the follow-ups before final restoration. Surgical extraction of impacted canines may be an alternative treatment option, when orthodontic extraction is not indicated. Although, as always surgical procedures are expensive and patient comfort is lower than orthodontic treatment.
